Barbara Gillespie Pickard (1936-2019) studied plant electrophysiology and mechanosensory biology for more than 50 y. Her first papers on the roles of auxin in plant tropisms were coauthored with Kenneth V. Thimann. Later, she studied plant electrophysiology. She made it clear that plant action potentials are not a peculiar feature of so-called sensitive plants, but that all plants exhibit these fast electric signals. Barbara Gillespie Pickard proposed a neuronal model for the spreading of electric signals induced by mechanical stimuli across plant tissues. In later years, she studied the stretch-activated plasma membrane channels of plants and formulated the plasma-membrane control center model. Barbara Pickard summarized all her findings in a new model of phyllotaxis involving waves of auxin fluxes and mechano-sensory signaling.
芭芭拉·吉莱斯皮·皮卡德（Barbara Gillespie Pickard，1936-2019）从事植物电生理学和机械感觉生物学研究超过 50 年。她最早的几篇关于植物向性中生长素作用的论文是与肯尼斯·V·蒂曼（Kenneth V. Thimann）合著的。后来，她研究了植物电生理学。她明确指出，植物动作电位并不是所谓的敏感植物所特有的，而是所有植物都表现出这些快速电信号。芭芭拉·吉莱斯皮·皮卡德（Barbara Gillespie Pickard）提出了一个神经元模型，用于解释机械刺激诱导的电信号在植物组织中的传播。在后来的几年里，她研究了植物的拉伸激活的质膜通道，并提出了质膜控制中心模型。芭芭拉·皮卡德（Barbara Pickard）在一个新的叶序模式中总结了她所有的发现，该模式涉及生长素流和机械感觉信号的波动。
